A 39for39 loop to iterate over an enum in Java

Questions

I have an enum in Java for the cardinal & intermediate directions:

public enum Direction {
   NORTH,
   NORTHEAST,
   EAST,
   SOUTHEAST,
   SOUTH,
   SOUTHWEST,
   WEST,
   NORTHWEST
}

How can I write a for loop that iterates through each of these enum values?

Answers

.values()

You can call the values() method on your enum.

for (Direction dir : Direction.values()) {
  // do what you want
}
